Answer:
Explanation:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

What will happen to the parts of the cricket as it travels through the digestive system?
Are there any concerns about certain people consuming crickets?
Answer:
it would be broken down
Explanation:
the digestive systems purpose is to break down food into energy
As the food goes from the very first part of the digestive system it reaches the last part as in its most digested form. The situation is possible because of the digestion.
What is the very first organ of digestive system ?It is the mouth that is solely making enough of digestion as it contains the amylase which is responsible for the digestion of starch.
As the food reaches the mouth it gets mixed with saliva which makes it easier to get break into and the food in this condition is called as bolus where the food will enter into the esophagus that is the food pipe via the peristalsis where the inward and outward movement of food pipe makes it enter the stomach.
In stomach the process of churning takes place where it gets mixed with the digestive juices and the food mixing with the digestive juices breaks into its simpler constituents.

Quail use feathers for thermoregulation, flight and camouflage. What type of adaptation are feathers?
A. Structural
B. Behavioral
C. Physiology
D. Feathers are not an adaptation
Answer:
structural
Explanation:
In addition to flight and body feathers, birds also have down feathers. Down feathers are soft and fluffy because they don't have barbules and barbicels (the structures that hook feather barbs together). Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.

Which of the following correctly lists the parts of the water cycle?
A) Evaporation, condensation, temperature, precipitation, collection
B) Condensation, build-up, runoff, precipitation, collection
C) Runoff, precipitation, evaporation, melting, condensation
D) Evaporation, condensation, precipitation, runoff, collection
Explain why
Answer:
D) Evaporation, condensation, precipitation, runoff, collection
Please give me brainlyest
Explanation: The water cycle shows the continuous movement of water within the Earth and atmosphere. System that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Then I does runoff and creates a new water source or goes back to a water source.

5. How is this different from Darwin's idea of fitness?
Answer:
Darwinian fitness differs from the “physical fitness”, which is more associated with health, muscle tissues, oxygen, and physical effort. Darwinian fitness is more concerned about reproductive success. Darwinian fitness describes how successful an organism has been at passing on its genes.
Does natural selection affect humans? How and why
Answer:
Yes it does affect humans.
Explanation:
Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.

1. An atom of which element has 37 protons, 48 neutrons and 1 valence electron? Answer:
Answer: Rubidium
Explanation:
The atom with 37 protons, 48 neutrons, and 1 valence electron is Rubidium (Rb).
Which element has 37 protons, 48 neutrons, and 1 valence electron?Rubidium (Rb) is the element that has 37 protons, 48 neutrons, and 1 valence electron. Protons and neutrons are located in the nucleus of an atom, while valence electrons are found in the outermost energy level or shell.
In the case of Rubidium, it has 37 protons which defines its atomic number and element identity. Also, it has 48 neutrons which contribute to its atomic mass. The valence electron of Rubidium is in the outermost energy level making it readily available for chemical reactions and interactions with other atoms.

Zebrafish (Danio rerio) is an important model organism in the field of genetics. One of the first mutant genes to be studied in this species was golden. The mutant allele was discovered in a pigmentation mutant purchased from a pet store, which changed the color of the fish from the wild-type silver-white coloration to a pale golden color. Calculate the percent likelihood of golden offspring from a cross between a heterozygous wild-type male fish to a golden female fish a 0% b 50% c 25% d 100%
Answer:
b
Explanation:
Let the wild type trait, the silver-white, be represented by A allele and the mutant trait, the golden color, be represented by a allele.
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
Hence, the percent likelihood of golden offspring is 2/4 or 50%.
The correct option is b.

Which two parts of the water cycle involve water in its gas form?
A) Condensation and collection
B) Evaporation and condensation
C) Precipitation and condensation
D) Runoff and evaporation
Explain why.
Evaporation and condensation involve water in its gas form. Hence, option B is correct.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle. It is a very important cycle for the survival of living organisms.
The water cycle is composed mostly of four processes: evaporation, convection, precipitation, and collection. When the water in rivers, lakes, or the ocean is heated by the sun and turned into vapor or steam, this process is known as evaporation. In condensation, water vapors are converted into water.
The parts of the water cycle that involve water in its gas form are evaporation and condensation. Hence, option B is correct.

Choose a statement that explains why competitive exclusion occurs between different species.
Limited resources are easily shared.
There are unlimited resources in the ecosystem.
Competition decreases the health of all animals.
One competitor is best at using a limited resource.
The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.
What is competitive exclusion?It is the result of the competition in which a species is expelled by another more efficient species from a part of the available habitat.
Characteristics of the competitive exclusionThe competitive exclusion principle states that two species cannot occupy the same ecological niche in the same habitat.If there are limited resources, eventually one species will exclude the other, given a certain period of time, through “competitive exclusion”.Therefore, we can conclude that the competitive exclusion states that two species occupying the same niche cannot coexist in the long term since they would enter into competition for limited resources.

explain whether the following statement is true or false: “All arteries carry blood with oxygen and all veins carry blood with carbon dioxide.”
Answer:
False
Explanation:
Important parts of circulatory system are heart, capillaries, veins, and arteries. The arteries are responsible for carrying red blood from heart and deliver oxygen to capillaries. Then capillaries deliver the waste carrying blood or deoxygenated blood to veins back to the heart.
But not all arteries carry blood with oxygen, the pulmonary arteries carry deoxygenated blood and not all veins carry blood with carbon dioxide, the pulmonary veins carry blood with oxygen.
Hence, the given statement is true.
